Will also say that I've got these exact springs and they're great :) Had them for 2 years now.

I've got the inverted RM ones and I find them fine for road use. Dampers are on 15/32 front and 20/32 rear at the moment. Haven't adjusted them very much but they're ok for now. Will play around a bit more with the settings later. Next track day is in about 1 month so I'll report back after that.

That's interesting Adrian. I was going to go the inverted RM's but the guy from just jap talked me out of it. They said they would to aggressive for the street. The test for the BC's will be to see if they last as long as a set of Tein's there's not many out there that can

But RM Inverted has less unsprung mass hehe
Did a bit more googling and seems like the other car forums agree that BC BR coilovers are great for street and tracking. BC seems to have earned a very good rep despite being relatively new brand. Skyline guys had no issues with maintence either (fellow running 30,000km+/3 months no prob)
I had a read through this, quite interesting

Mentions coilovers in general being high maintence, anyone had leak issues?
 

I heard their re badged as Greddy coil overs

I received mine today and installed them. They feel really nice, ive done about 50kms on them so far with no complaint. At the moment I have them as they came height and preload wise and adjusted the damping to 10 front and 16 rear. These are more comfortable then the lowered springs the car had before.

NB: Check the legality in your state as they are highly defectable in SA as most of them are height adjustable. 

what pre-load are you guys running on your BC BR's? I was inspecting mine on the hoist and they aren't setup from factory at all. they are all inconsistent. So I will adjust them tomorrow. 

The height on mine was spot on for factory setting. I set damper to 0 as a starting point.

I put 4mm preload on all 4 corners and lowered it yesterday. Its just above legal height. I would like it lower but I dont want to attract attention!
